In modern times, diesel generators have become indispensable power equipment in many industries. Diesel generators can provide continuous and stable power supply when the grid is out of power, and they will not be forced to stop work and production in case of power outages. So, how to choose the right one? What about your own diesel generator? Should I choose a single-phase generator or a three-phase generator? To give you an idea of the difference between the two types of diesel generators, we have put together a quick but informative guide covering the main differences between the two types of diesel generators for you to refer to when choosing a generator .
Single-phase (1Ph) diesel generators require one of the following cables (line, neutral, and ground) and typically run on 220 volts.As the name implies, a three-phase (3Ph) generator uses three live cables, a ground wire, and a neutral wire. These machines typically run on 380 volts.
The main difference between single-phase and three-phase diesel generators 1.Number of conductors
We’ve touched on this above, but it’s an important point. Single-phase diesel generators use only one conductor (L1), while three-phase diesel generators use three (L1, L2, L3). Our advice to our customers is to match diesel generator equipment to their application, so determining what they want to achieve is always the first step.
2.power generation capacity
The number of conductors in use has a positive impact on the overall power production capacity of a diesel generator. For this reason, three-phase diesel generators have higher output ratings because (regardless of the diesel engine and alternator) they can provide three times the output. For this reason, for industries such as commercial or industrial, we generally recommend three-phase diesel
generators.
3.application use
Single phase diesel generators are best suited for jobs with lower power output requirements and are therefore often used in family homes, small events, small shops, small construction sites, etc. Three-phase diesel generators are more suitable for larger applications, so we often see these diesel generators commonly used in commercial locations, industrial locations, marine environments, construction sites, hospitals, and many other locations.
4.Reliability and Durability
Power continuity is arguably the most important element of any power solution. This rule applies regardless of whether the generator is used for primary power use or for backup power. With this in mind, single phase diesel generators have the obvious inherent disadvantage of operating with only one conductor. So if that one cable or ”phase” fails, the entire power solution is rendered useless.
For three-phase diesel generators, in certain fault conditions, if one of the phases (eg L1) fails, then the other two phases (L2, L3) can keep running to ensure continuous power supply.
In mission critical applications, it is recommended to reduce this risk by combining two diesel generators (1 operational, 1 standby) for an N+ 1 redundant setup.
